I'm working on an AngularJS and Rails app that uses Google's definition API. The API returns a JSON response.
I would like to store the JSON response in my Words table. I'm issuing the API request through my Angular controller, then I'm trying to add the data to my Words table.
I'm getting an "Unpermitted parameters" error when I try to insert the JSON data. I've researched and this seems to be due to Rails 4 nested params.
I've tried adding nested brackets to my word_params method in Words controller but then get "Unpermitted parameters: dataType, numToShow, groupNumber, groupResult, sectionType, dictionary"... which is part of the API response.
Is there an easier way to permit the full JSON data without having to go through and specifically define each nested param in the controller's word_params method?
scheme.rb
create_table "words", force: :cascade do |t|
t.string "title"
t.json "full_data"
t.integer "list_id"
t.datetime "date"
end
Word controller
class WordsController < ApplicationController
respond_to :json
def create
list = List.find(params[:list_id])
word = list.words.create(word_params)
respond_with list, word
end
private
def word_params
params.require(:word).permit(:title, :date, :full_data => {})
end
end
